The consideration of uncertainties in numerical models to obtain the probabilistic
descriptions of vibration response is becoming more desirable for industrial scale finite
element models. Broadly speaking, there are two aspects to this problem. The first is the
quantification of parametric and non-parametric uncertainties associated with the model and
the second is the propagation of uncertainties through the model. While methods of
uncertainty propagation have been extensively researched in the past two decades (eg, the …
